Class DynAnyFactoryHolder

java.lang.Object
org.omg.DynamicAny.DynAnyFactoryHolder
All Implemented Interfaces:
Streamable
public final class DynAnyFactoryHolder extends Object implements Streamable
DynAny objects can be created by invoking operations on the DynAnyFactory object. Generally there are only two ways to create a DynAny object:
  • invoking an operation on an existing DynAny object
  • invoking an operation on a DynAnyFactory object
A constructed DynAny object supports operations that enable the creation of new DynAny objects encapsulating access to the value of some constituent. DynAny objects also support the copy operation for creating new DynAny objects. A reference to the DynAnyFactory object is obtained by calling ORB.resolve_initial_references() with the identifier parameter set to the string constant "DynAnyFactory".

Dynamic interpretation of an any usually involves creating a DynAny object using create_dyn_any() as the first step. Depending on the type of the any, the resulting DynAny object reference can be narrowed to a DynFixed, DynStruct, DynSequence, DynArray, DynUnion, DynEnum, or DynValue object reference.

Dynamic creation of an any involves creating a DynAny object using create_dyn_any_from_type_code(), passing the TypeCode associated with the value to be created. The returned reference is narrowed to one of the complex types, such as DynStruct, if appropriate. Then, the value can be initialized by means of invoking operations on the resulting object. Finally, the to_any operation can be invoked to create an any value from the constructed DynAny.

      Parameters:
      i - the InputStream that represents the CDR data from the wire.

    • _write

      public void _write(OutputStream o)
      Description copied from interface: Streamable
      Marshals to ostream the value in the value field of the Holder.
      Specified by:
      _write in interface Streamable
      Parameters:
      o - the CDR OutputStream

    • _type

      public TypeCode _type()
      Description copied from interface: Streamable
      Retrieves the TypeCode object corresponding to the value in the value field of the Holder.
      Specified by:
      _type in interface Streamable
      Returns:
      the TypeCode object for the value held in the holder
